Description

[Detailed explanation of the idea] [Industrial application field] This invention relates to a wall plate joining structure.

[Conventional technology]

Conventionally, when building exterior walls with inorganic wallboards,
A large-area wall is constructed by sequentially joining wall plates of a certain length and width.

In this case, a waterproof jointer material is generally inserted between the wall panels and the joints to prevent rainwater from entering from the outside.

As a conventional waterproof jointer material, a material A made by bending a thin metal plate in a stepwise manner as shown in FIG. 4 has been used.

[Problems with conventional technology]

However, as shown in FIG. 4, wall board material B is sometimes used with deeply carved uneven patterns P and Q on the surface, and in such cases, conventional waterproof jointer material A is not sufficient. One drawback was that it could not be drained.

That is, in the conventional joiner material A, when the downwardly extending portion _A1 of the joiner material A is extended onto the lower wall plate B, the jointer material extending portion is as shown in FIG.
A space S is formed between the back surface of A ₁ and the surface of wall board B due to the uneven patterns P and Q, and rainwater may be blown in from this space, and this may infiltrate into the back surface of wall board B due to capillary action. be.

[Problems solved by invention]

In view of the above-mentioned problems, this invention provides a wallboard joining structure that can reliably perform waterproof joining, even if the surface of the wallboard has a deeply carved uneven pattern. It was done for the purpose of

[Technology to solve problems]

That is, in the wall board joining structure of this invention, the flat plates 1, 1 having an uneven pattern are arranged vertically along the wall base 4, and the upper end of the surface 2 of the lower wall plate 1 is higher than the height of the uneven pattern. , the wall plate is cut in the thickness direction to form a band-shaped flat surface 2A, and between the upper and lower wall plates, an outer surface 3A protrudes from the surfaces of the wall plates 1, 1 and has a rectangular cross section, and an inner surface 3B is formed between the upper and lower walls. A lip part 30 inserted into the abutting part of the boards, a flat part 31 along the cutting flat surface 2A of the lower wall board, and a downwardly extending part 3 toward the envelope flat surface 10 of the top of the convex pattern on the surface of the lower wall board.
A joint material 3 formed stepwise between the upper wall board 1 and the wall base 4 is inserted along the outer surface of the lip part 30 of the joint material between the back surface of the upper wall board 1 and the wall base 4. A jointer material 5 made of a bent thin metal plate is inserted to reach the upper cutting flat surface 2A, and the flat surface 31 is filled with a sealing material 6.

〔Example〕

Next, this invention will be explained using examples.

Figure 1 is a sectional view of an embodiment of this invention, Figure 2 is a sectional view of an embodiment of this invention;
3 are perspective views of essential parts of the embodiment.

In the wall board joining structure of this invention, wall boards 1 having uneven patterns P and Q are arranged one above the other as shown in FIG.
The wall board 1 is cut in the thickness direction (arrow A lip portion 3 that protrudes and has a rectangular cross section, and whose inner surface 3B is inserted into the abutting portion of the upper and lower wall plates 1, 1.
0, a flat part 31 along the cut flat surface 2A of the lower wall board 1, and a downwardly extending part 32 along the envelope flat surface 10 of the top of the convex pattern P on the surface of the lower wall board 1, as shown in the figure. A joint material 3 formed in a shape is inserted, and the upper cut flat surface 2A of the lower wall board 1 is inserted along the outer surface of the lip portion 30 of the joint material 3 from between the back surface of the upper wall board 1 and the wall base surface 4. A jointer material 5 formed by bending a thin metal plate is inserted, and the flat surface portion 31 is filled with a sealing material 6.

In addition, 7 and 7 in a figure are the nails which fix the wall boards 1 and 1 to the wall base 4.

In the above embodiment, the uneven pattern on the surface of the wall board 1 may be a vertical striped uneven pattern as shown in FIG. 2 or an at random uneven pattern as shown in FIG. 3. It is possible.

Next, the method of constructing the wall-board joint structure of this invention will be explained.

First, the upper surface of the wall board 1, which will become the lower wall board, is cut along the upper edge using a grinder or the like to at least the height of the convex pattern P, thereby forming a band-shaped flat surface 2A.

Next, this wall board 1 is applied to the wall base 4, and the applied lower wall board 1 is fixed with nails 7 via the previously prepared joiner material 5, joint material 3, and sealing material 6, and then the upper wall The board 1 is placed on the joint material 3, applied to the wall base 4, and fixed with nails 7.

[Effect]

In the wall board joint structure of this invention, the uneven pattern on the wall board surface is cut flat at the upper end of the wall board 1, and the flat part 31 of the joint material 3 is closely contacted with this part through the sealing material 6. Since they are in contact with each other, even if there is a gap between the downwardly extending portion 32 of the joint material 3 and the uneven pattern on the surface of the wall board 1, this will be completely closed.
Rainwater is prevented from penetrating into the back surface of the wall board 1.

〔effect〕

As explained above, this invention can completely eliminate water leakage caused by unevenness even if the wallboard has an uneven surface pattern, and can be joined to the wallboard. Since it extends to the surface, the joint part looks good and has various practical effects, such as a good appearance.
